EDWIN BALL STIMPSON, OF BROOKLYN, NEW YORK.

CARTRIDGE-BELT.

To all whom it may concern: Be it known that I, EDWIN BALL'STIMP- soN, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain newand useful Improvements in Cartridge Belts, of which the following is a specificatlOIl.

My invention relates to cartridge belts of the particulartype that is adapted for use in feeding cartridges to the loading mechanism of machine guns.

Cartridge belts of this general nature such as have been heretofore known in the art have invariably been constructed of comparatively thick and heavy material'of a woven texture that not only added considerably to the volume occupied by the packed cartridges, but also added very materially to the expense of manufacture. It will be apparent that it is of prime importance that the bulk V a great extent eliminated.

taken up by the cartridge supply be restricted as far as possible'because of the transportation difficulties that arise in the operation of the machine guns in the advanced .and exposed positions in which they are usually mounted in modern methods of warfare. It

:is also important that the cost of manufacture of thebelt be kept as low as possible sible, it will be seen that the wastage of ma terial adds enormously to the expense of producing this form of cartridge belt.

The main object of the present invention is; to provide a cartridge belt made of comparatively thin and inexpensive material in order that the objections pointed out as being attendant uponthe use ofbelts as known and used in the prior art maybe to With this and other objects in view, one feature of the invention consists in the pro vision of a cartridge belt constructed of comparatively unsubstantial and inexpensive sheet material, such as paper or light cotton or other fabric. and having means included therein for substantially reinforcing said belt in a plurality of zones along its length.

Application filed May 9, 1913. Serial No. 233,553.

templates the attachment of two strips of material of the character referred to to each folded or doubled over strips of the material to thereby form a belt member having the requlsite strength, and in arranging two such members in a face to face relation and in stitching the corresponding threads of the respective members to each other at intervals to form cartridge holding loops.

Another feature of the invention resides in the use of metallic clip members for attaching the belt members to each other to form the cartridgeholding loops.

Still another feature of the invention resides in providing longer points of attach- -ment of the members to each other at one edge of the belt than the other so as to provide loops correspondingly reduced in size to fit the smaller end of the cartridge.

- Otherfeatures of the invention will be hereinafter described.

In the drawings,

Figure 1 is a view of a portion of a cartridge belt embodying a preferred form of the invention and showing a number of cartridges in place therein.

Fig. 2 is an enlarged sectional view taken along the line 2-2 of Fig. 1.

Fig. 3 is a sectional view taken at right angles to the view shown in Fig. 2 and along the line 33 of Fig. 1.

Fig. 4 is a fragmentary view of a belt showing a modified form of the invention.

Fig. 5 isan edge view of the form of belt shown in Fig. 4.

Fig. 6 is a fragmentary view of still another modification of the invention.

Fig. 7 is an edge view of the form of belt shown in Fig. 6.

Fig. 8 is a sectional view taken along the line 88 of Fig. 6. Fig. 9 is a sectional view of one of the str s comprisingthe form of belt shown in Fig. 6. i

The cartridge feeding belt shown in the drawings comprises the strips 1 and 2 formed of any suitable sheet material of an unsubstantial and inexpensive nature. such as paper or light cotton or other fabrics, and having the cords or threadsB embedded therein for the purpose of increasing the tensile strength of the belt as a whole. The cords 3 are preferably arranged at the two lateral margins of the strips and along the 7 central axis thereof, so that an ample mar.-

gin of strength is provided' to withstand the operation of the feeding mechanism and prevent the breaking of the belt as it is drawnthrough the breech mechanism to provide for the feeding of'the cartridges therefrom into the chamber of the gun.

In order to provide loopsor pockets in the belt structure in which the cartridges may be received, the two strips of material 1 and 2 are attached together at the proper intervals to provide loops of the desired size by means of groupsof stitches 4: and 5 that arearranged to embrace the corresponding separated portions of the'reinfor-cing cords and the particular portions of the sheet ma- 7 While in thepreferred embodiment of the invention three reinforcing cords are used, as shown in Fig. 1 it is possible to make use of but two cords as indicated in Fig. l of the drawing; With this form of construction the cartridge is held at only two points near theends and theentii'e length of the cartridge intermediate thereto" is loosely held so as to offer a minimum; degree of resistance to the operation of removing the cartridges from the corresponding loops In the two forms of'the invention a ready described it will be seen by reference, to

It, will be seen that a cartridge belt has been provided that may beconstructed 0f unsubstantial and inexpensive material such as paper, and which will nevertheless offer an adequate resistance to being torn as it is drawn through the feeding 'mechanism of a un. a Having thus described my invention, "what Iclaim and desire to secure by Letters .Pat-
